Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688072, here are decompositions:

5 + 8688067 = 8688072
13 + 8688059 = 8688072
59 + 8688013 = 8688072
61 + 8688011 = 8688072
79 + 8687993 = 8688072
89 + 8687983 = 8688072
109 + 8687963 = 8688072
149 + 8687923 = 8688072

Showing the first eight; more decompositions exist.
